### What is the problem the feature request solves? Hello! I need to measure actual off-heap memory changes to determine how much is required. I've tried several approaches: - JProfiler shows small Non-heap values - MBean java.nio.BufferPool.direct also shows small values - jcmd 15 VM.native_memory summary with -XX:NativeMemoryTracking=summary flag gives some non-actual small values - The res value from top command for the Java process seems more accurate, but it includes heap memory as well. Is there a way to get the pure off-heap memory value that is currently occupied? Also, are there methods to collect thread data from native memory similar to how it's collected from JVM? So far I've only managed to profile native code using async-profiler. ### Describe the potential solution _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
